I'm a software and electrical engineer and triathlete, but haven't (yet) had need to dig in with CIQ. One reason I was excited to upgrade from my F3 to the FR935 is BLE sensor support, but I guess that's still in a very basic, early phase? I've got a BLE sensor I'd love to pull data from in either an app or a datafield, but it seems to be the case that there aren't any APIs for communicating with sensors over BLE, only for communicating with a phone.
Is it true that you can interface with custom ANT+ hardware, but not yet custom (or even generic) BLE hardware?
